TABLE 15-6 Given Below Are Results from the Regression Analysis on 40

question 78

Short Answer

TABLE 15-6
Given below are results from the regression analysis on 40 observations where the dependent variable is the number of weeks a worker is unemployed due to a layoff (Y) and the independent variables are the age of the worker (X₁), the number of years of education received (X₂), the number of years at the previous job (X₃), a dummy variable for marital status (X₄: 1 = married, 0 = otherwise), a dummy variable for head of household (X₅: 1 = yes, 0 = no) and a dummy variable for management position (X₆: 1 = yes, 0 = no).
The coefficient of multiple determination (R) for the regression model using each of the 6 variables Xⱼ as the dependent variable and all other X variables as independent variables are, respectively, 0.2628, 0.1240, 0.2404, 0.3510, 0.3342 and 0.0993.
The partial results from best-subset regression are given below:

-Referring to Table 15-6, what is the value of the variance inflationary factor of Married?

Definitions:

Test Statistic

A calculated value used to determine whether to reject the null hypothesis in statistical hypothesis testing.

Critical Value

A point on the scale of a test statistic beyond which we reject the null hypothesis; it depends on the chosen significance level.

Test Statistic

A value calculated from sample data during a hypothesis test.

Null Hypothesis

A hypothesis that states there is no difference or effect, serving as the default assumption to test against in statistical hypothesis testing.
